Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size is 1/2 inch. Roll crushers will only crush material down to a …
Manufactured sand made by roll crusher in Indonesia. The video shows the double roller crusher is turning small-sized stones into manufactured sand. There is a certain gap between the two counter-rotating rollers. Changing the gap can control the product size, shapes, and fineness modulus. Because it can produce high-fineness …
It has a jaw crusher, a two deck screen and a roll crusher, all of which would be difficult to work on, even to change a screen cloth on the top deck of the screen. The only advantage I see in it is you can move everything in one trip, whereas with separate components you'd have 4 loads, which would consist of the jaw, screen, roll crusher and ...
